Soil Pile Set-Up Of Driven Pile In Clay.
PhD thesis, Perpustakaan Hamzah Sendut.
Abstract
Soil/ pile set-up is a phenomenon of pile capacity increase in a driven pile as time
passes which is often ignored. Incorporation of set-up effect in routine designing of
piles could result in saving due to smaller required section or lesser driving energy.
This research was carried out to study if small cylindrical metal piles with diameters
ranging from 12.0 mm to 75.5 mm that were driven in the field and cylindrical metal
rods with diameters ranging from 9.4 mm to 25.6 mm that were tested in laboratory,
were capable of measuring set-up parameters of actual working piles and
determining factors that affect set-up in clays. The field tests have involved depths
ranging from 1.0 m to 9.8 m and periodical data readings of up to 350 days while the
laboratory tests have had 450 mm of horizontal penetrations and data collection for
up to 28 days. In addition, the field tests have also included square reinforced
concrete piles, 300 mm to 400 nun in thicknesses, and driven to a depth of9 m. Two
sites have been used for the tests namely within the campuses of Universiti Sains
Malaysia in Nibong Tebal, Pulau Pinang and Universiti Teknologi Mara in
Permatang Pauh, Pulau Pinang.
